5G UE Beam Selection for Congestion and Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication networks, multiple user equipment (UE) accessing the same communication beam leads to beam overload, reducing information transmission quality and user experience due to channel congestion.
Innovation Solution
User equipment acquires and orders beam information based on signal intensity, selecting the strongest beam for connection while considering current state information to avoid channel congestion and ensure reliable network access, and automatically reselects beams if initial connections fail or data transmission is poor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all terminals select the same beam for network access, then the beam can provide service to maximum number of terminals, but beam overload occurs causing channel congestion and reduced transmission quality
Solution Approach 1:
The patent segments the beam selection process by introducing multiple beam groups (first beam group and second beam group) with different characteristics. Terminals are segmented into different categories based on their requirements, with some terminals selecting from first beam group and others from second beam group, thereby distributing the load across multiple beams while maintaining service capacity.
Solution Approach 2:
The patent changes the selection parameters by introducing beam group identifiers and different selection criteria for different beam groups. Instead of all terminals using the same beam selection parameter (maximum signal strength), terminals in different groups use different parameters, allowing the system to balance between serving capacity and transmission quality.
2Reliability
If user equipment continuously detects and reselects beams to ensure optimal connection, then network connection reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic beam detection and reselection mechanisms rather than continuous operation. The terminal performs beam detection at specific intervals or under specific triggering conditions (such as when signal quality degrades below a threshold), thereby maintaining connection reliability while significantly reducing power consumption compared to continuous monitoring.
Solution Approach 2:
The terminal autonomously determines when beam reselection is necessary based on predefined criteria (signal quality thresholds, connection status), eliminating the need for continuous network-controlled beam management. This self-service approach reduces signaling overhead and allows the terminal to optimize its own power consumption while maintaining reliable connection.
